Pile In! finds your nearby friends so that you can share rides for free. Simply enter your starting location and ending destination and Pile In! does the rest to find your nearby friends to request or offer rides for free.
If none of your friends is nearby or can give you a ride, you can see nearby Lyft or Car2Go cars available to get you to where you want to go.
